Application filed ,ffliareh 25,1921. Serial No. 455,476.

To, all whom it may concern Be it known thatI, HENRY M. SHEER, re-

siding at Quincy, in the county of Adams.

and State of Illinois, a citizen of the United States, have inventedcertain new and useful Improvements in Heating Systems for Brooders,Incubators, and the like, of which the following is a specification.

This invention relates to heating systems for brooders, incubators, andthe like, and

one object is to provide, in combination with a visiblemanually-operated oil-feed, a means to facilitate the initial startingof the burnerby which, after the predetermined depth of the oil in theburner for starting is effected and the burner lighted, the operator isassured of nothing greater than the predetermined feed of oil to theburner.

Another object of the invention is to provide an overflow means, bywhich the burner proper is prevented from overflowing, causing a messunder the canopy or around the incubator in case the flame should accidentally go out. 4 I

In the accompanying drawings Fig. 1 is a perspective view of my completedevice; i

Fig. 2 is an enlarged detail view of the overflow arrangement.

The numeral 1 indicates a burner, connected to which is an oil-font 2supported by a base 3, by means of a vertical feed-pipe 4.

"Leading from the base is a horizontallyarranged feed-pipe 5, the majorportion of which is arranged horizontally andin close proximity to thefloor, allowing free movement of the chicks beneath the canopy when usedin connection with that type of broode'r. Said pipe 5 is supported nearits outer end by a bracket 6, which, together with the base 3, providesa suitable support for the heating "system. The outer end of the feed-)pipe 5 is preferably bent upwardly, and then horizontally as at 5 justprior to enter ing the burner, acting as a support for the burner. Theoil-font 2 is preferably provided with suitable brackets 7, which areadapted to receive an oil reservoir 8, which, in this instance, is madeof glass, provided with stopper controllin mechanism 9 adapted to beactuated a ter the glass reservoir is inverted and itsopen end placedwithin the oil font2. Abracket 10 is adapted to directly support the oilfont, said bracket having formed in its outer end a visible oil chamber11.

-Mou-nted upon the bracket 10 directly above the visible oil feed is acasting 12, having arran'ged horizontally therein a spring actuatedneedle valve 13. The casting 12 is provided with an upwardly andhorizontally projecting arm 14 at the top, and this carries a minimumand maximum adjusting located at a point where they are easilyaccessible and easy to manipulate. At its lower end, and beneath thevalve 13, the casting has a pair of lugs 14.

The valve-controlling lever 18 is fulcrumed between these lugs 14 on thepin 19, the arm of this lever above the fulcrum extending in the pathof, and in close proximity to, the protruding end of the needle-valve13, and its extreme upper end in the space between the inner end ofvtheminimum and maximum adjusting screws 15 and 16, by which its adjustmentis regulated. An auxiliary lever 20 is also fulcrumed on the pin 19alongside the controlling lever 18, and its upper end also extends intothe path of the protruding end of the needle-valve 13.

Thus auxiliary lever 20 has a flange 21 at one edge, which overlaps theouter edge of the lever 18, so that when lever 18' is swung in onedirection, the auxiliary lever 20 moves .screw 21 screws into thethreaded eye 22 of the lower end of the auxiliary lever 20. By

means of the auxiliary lever, the needlevalve can be opened or closedwithout deranging or changing in the least the position of the minimumor inaximum adjustingscrews 15 and 16 at the top of the valve. Withoutthis auxiliary adjustment 21, it is necessary to use the maximumadjusting screw to close the needle-valve 13 and shut off the oil. 'Ofcourse, this also makes it necessary to change the position of theminimum adjusting screw 15.

' Arranged adjacent the burner is a thermostatic regulator 23, which isadjustably supported uponthe feed-pipe bracket 6. The

' adjusting-lever 24 of the thermostat and the screw, 15 and .16,respectively, they being relative movement to the spring-valve 18. As isapparent, the visible oil feed enables the operator to determine boththe minimum and maximum flow of oil, counting the number of drops of oilpassing through the visible oil-chamber, and it is not necessary for.the operator to wait for the flames to fully respond to prevent apossible overflow of the burner in case the flame should beextinguished, or that there were too great a flow of oil for the burnerto properly consume, for I connect to the vertical feed-pipe 4 anoverflow valve 26, which, as shown in Fig. l, is at such an elevationalong the feed-pipe 4 as to be in horizontal alignment with the outerhorizontal portion 5 of the horizontal feed-pipe 5. Arranged directlybeneath this valve is a suitable receptacle 27 removably secured to thebase 3 on the vertical feed-pipe 4, which is adapted to receive theoverflow from the valve 26, thereby preventing any oil spilling over atthe burner.

The operator in starting up the heater will level it so that when theoil ceases'to run out of the overflow valve 26, it will show apredetermined depth in the bottom of the oil groove in the burner 1.After securing this level, the o erator will close the overflow valve26, prlming the burner 27 with gasoline, lighting it, and waiting a fewseconds for the flame to get started. Then he will turn on the oil inthe visible oil feed so it will give the burner the proper number ofdrops for the size flame desired.

The overflow valve 26 is then opened, and the operator can immediatelygo away, and the burner'takes care of itself, the overflow taking careof any possible excess flow above a certain predetermined level, andalso taking care of the natural flow should the flame for any reason beaccidentally ex-L tinguished.

It will thus be seen that T have provided an overflow or regulatingmeans of simple character, which, in combination with themanually-actuated valve-mechanism and visible feed produce an apparatuswhich is practically automatic, doing away with practically all personalattention on the part of the operator, after the burner is initiallystarted.

I claim: v

1. A heater com rising a burner adapted to burn a liquid llel, areservoir for the liquid, automatically controlled means interposedbetween the reservoir and the burner for regulating the fuel supply tothe burner, and an overflow interposed between the reservoir and theburner and arranged in horizontal alignment with the oil groovebetweensaid burner and reservoir, the portion thereof adjacent the reservoirarranged vertically, oil-controlling means ar ranged adjacent thereservoir, and an overflow means arranged in the vertical portion of thefeed-pipe in horizontal alignment with the oil level in the oil grooveof the burner. v v

3. A portable heating system comprising a base, a container arrangedabove said base, a burner, a feed-pipe arranged between said containerand burner, portions thereofadjacent the container arranged vertically,oilcontrol means arranged adjacent the container, and an overflow valvearranged in the vertical portion of the feed-pipe adjacent the containerin horizontal alignment with the oil levelin the oil groove of theburner.

4. The combination of an oil container, a base, I a burner, feed-pipesarranged between said base, container and burner, the

pipe extending between the base and burner arranged in close proximityto the floor, oil controlling means interposed between the container andburner, an overflow valve arranged in the feed-pipe extending betweenthe container and burner arranged in horizontal alignment with the oilgroove of the burner.

5. A heater comprising a burner adapted to burn a liquid fuel, areservoir arranged above the burner, a feed-pipe connected between saidburner and reservoir, a portion thereof adjacent the reservoir arrangedvertically, oil controlling means arranged adjacent the reservoir, asight-feed interposed between the reservoir and burner, and an overflowmeans arranged in the vertical portion of the feed-pipe below thesight-feed and in horizontal alignment with the oil level in the oilgroove of the burner.

In testimony whereof I hereunto affix my signature.
